Polymer extrusion is a well-known industrial method used for producing plastic products in large quantities. It is a cost-effective and efficient way of producing plastic products such as pipes, tubes, films, and sheets. The process involves melting the polymer material and then forcing it through a die to shape it into a specific form. There are different types of polymer extrusion techniques that vary in terms of temperature, pressure, and other factors.
The 2nd edition of the book "Extrusion" is a comprehensive guide on polymer extrusion techniques that are used in the industry. The book is authored by Chris Rauwendaal, a prominent figure in the field of extrusion technology. The book covers various topics related to extrusion techniques and their applications, including polymer behavior, machinery, dies, processing, and troubleshooting.
The book starts with an overview of polymer materials and their properties, which is essential for understanding the behavior of polymers under different processing conditions. The section covers important topics such as molecular weight, thermal properties, and rheological behavior of polymers that are critical to successful extrusion processing.
The machinery section of the book covers different types of extruders and their components in detail. It includes topics such as screw design, heating and cooling systems, and feed systems. The section also provides information on the different types of sensors used for monitoring process variables such as temperature, pressure, and flow rate.
The die section of the book covers different types of dies used in polymer extrusion, such as coextrusion dies, profile dies, and blown film dies. The section provides detailed information on die design, optimization, and die flow simulation. It also covers topics such as die swell, melt fracture, and surface defects that commonly occur during extrusion processing.
The processing section of the book covers different stages of the extrusion process, including melting, conveying, mixing, and cooling. The section provides information on the different types of additives used in extrusion processing, such as lubricants, stabilizers, and antistatic agents. It also covers topics such as screw design optimization, screw wear, and feeding systems.
The troubleshooting section of the book covers common problems encountered during the polymer extrusion process, such as die buildup, surface defects, and dimensional stability issues. The section provides guidelines on how to diagnose and solve these problems using different techniques such as monitoring process variables and optimizing the extrusion process.
Overall, the "Extrusion" book is an essential reference guide for anyone involved in polymer extrusion processing. It provides in-depth information on the different techniques used in extrusion, including machinery, dies, processing, and troubleshooting. The book is written in an easy-to-understand language that is suitable for both beginners and experienced professionals in the field. Whether you are a researcher, engineer, or technician working in the polymer extrusion industry, this book is a valuable resource that you should add to your library today.
